Ethiopian forces pushed towards the capital of the rebel Tigray region on Wednesday, ignoring international appeals for talks to end the conflict and denying it was targeting any ethnic group.

Federal troops are locked in a two-week conflict against Tigray’s forces, which has killed hundreds on both sides, rocked the Horn of Africa, stirred ethnic frictions elsewhere in Ethiopia and sent 30,000 refugees fleeing into Sudan.

Prime Minister Abiy Ahmed has billed the offensive as a campaign to restore rule of law in the northern state of more than 5 million people, saying victory would come in days.

He launched the offensive on Nov. 4 after accusing Tigrayan forces of an attack on a government base in the region.
